SUMMARY OF THE INVENTION

The present invention relates to a method of treating a condition comprising administering a corticotropin releasing factor (CRF) antagonist in an amount effective to treat the condition, the condition being selected from the group consisting of:

a) disorders that can be treated by altering circadian rhythm; and

b) depression, further wherein a second compound for treating depression is administered, the second compound for treating depression having an onset of action that is delayed with respect to that of the CRF antagonist.

In another aspect, the present invention relates to a method for treating or preventing a cardiovascular disease that involves administering a CRF antagonist in combination with a non-CRF antagonist compound for treating the disease. The invention also relates to treatment of migraine or non-migraine headache by administration of a CRF antagonist in combination with a non-CRF antagonist compound that treats such condition and to treatment of emesis using a CRF antagonist in combination with a non-CRF antagonist compound for treating emesis.

DETAILED DESCRIPTION OF THE INVENTION

All patents, patent publications, and literature references cited herein are hereby incorporated by reference.

In one aspect, the present invention provides for treatment of disorders that can be treated by altering circadian rhythm, e.g., abnormal circadian rhythm, by administration of a CRF antagonist. Abnormal circadian rhythm treated according to the invention can be associated with several types of disorders, including, without limitation, time zone change syndrome, seasonal affective disorder, irregular sleep-wake pattern, delayed sleep phase syndrome, advanced sleep phase syndrome, non-24 hour sleep wake disorder, light-induced clock resetting, REM sleep disorder, hypersomnia, parasomnia, narcolepsy, nocturnal enuresis, restless legs syndrome, sleep apnea, dysthymia, and abnormal circadian rhythm associated with chronic administration and withdrawal of antidepressant agents.

If desired, a second compound, e.g., a non-CRF antagonist that is useful for treating sleep disorder, can be administered before, with, or after, administration of the CRF antagonist. Any such second compound useful for treating sleep disorder may be employed, including but not limited to tachykinin antagonists, melatoninergic agonists, such as melatonin, GABA brain receptor agonists, serotonin receptor (such as 5HT1b, 5HT2c, 5HT7) antagonists, inverse agonists, agonists and other compounds. Specific compounds for treatment of sleep disorder include melatonin, carpipramine, and doxylamine. These and other compounds are described, for example, in U.S. Pat. Nos. 5,908,932; 5,902,813; 5,883,094; 5,874,450; 5,849,781; 5,856,529; and U.S. Pat. No. 4,956,362.

It is intended that reference to particular compounds herein be interpreted to mean that the pharmaceutically acceptable salts and prodrugs of those compounds, may also be employed. Such reference is also intended to be interpreted that modified CRF antagonists may also be employed. For example, the invention encompasses use of a CRF antagonist linked to a non-CRF antagonist to form a prodrug which hydrolyzes upon administration to form active components.

The invention also encompasses treatment of depression with a CRF antagonist and with a second compound having delayed action for treating depression. According to this aspect of the invention, the CRF antagonist initiates treatment of the depression with a quick-acting effect, which treatment is supplemented by the delayed effect of the second compound.

Compounds for treating depression that have a delayed effect include, without limitation, compounds that are selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants, norepinephrine reuptake inhibitors, noradrenaline reuptake inhibitors, lithium, α2-adrenoreceptor agonists, 5HT_(1A) inhibitors, and monoamine oxidase type A inhibitors. Examples include bupropion, sertraline, fluoxetine, trazodone, citalopram, fluvoxamine, paroxetine, venlafaxine, roboxetine, imipramine, amitriptyline, trimipramine, doxepin, desipramine, nortriptyline, protriptyline, amoxapine, clomipramine, maprotiline, brofaromine, milnacipran, and buspirone. It understood by those skilled in this art that compounds administered for treatment of depression may have other beneficial effects, such as ameliorating sleep disturbance or sexual dysfunction. Compounds having a delayed effect for treating depression also include the combination of an SSRI and 5HT₂ antagonist (such as risperidone) administered, for example, to patients who do not respond to SSRI therapy alone. Administration of these delayed-action compounds for treating depression is carried out using well-known dosages and formulations.

Any CRF antagonist can be used to practice the invention, including those that are described in U.S. Pat. Nos. 4,605,642 and 5,063,245; International patent publications WO 95/33750; WO 95/34563; WO 94/13676; WO 94/13677; WO 95/33727; WO 98/05661; WO 98108847; and WO 98108846; and European patent publications EP 778277; and EP 773023.

Methods for making the CRF antagonists described above are disclosed in the above-listed patents and published patent applications incorporated by reference herein.

In an alternative embodiment, the present invention relates to a pharmaceutical composition for the treatment of a condition selected from the group consisting of:

a) abnormal circadian rhythm; and

b) depression.

The composition comprises an amount of a CRF antagonist effective to treat the condition in combination with a pharmaceutically acceptable carrier. Where the condition is depression, it is also treated with a second compound for treating depression, the second compound having an onset of action that is delayed with respect to that of the CRF antagonist.

In another aspect, the present invention relates to a method for treating or preventing a cardiovascular disease that involves administering a CRF antagonist, or a pharmaceutically acceptable salt, isomer, or prodrug thereof, in combination with a second, non-CRF antagonist compound for treating the disease. The second compound for treating the disease can be, for example, adenosine, alteplase, amiodarone, anagrelide, ardeparin, argatroban, atenolol, atorvastatin, benazepril, captopril, carvedilol, cerivastatin, clonidine, clopidrogrel, dalteparin, danaparoid, diltiazem, enalapril, fluvastatin, fosinopril, gemfibrozil, hydrochlorothiazide, irbesartan, lepirudin, lisinopril, lovastatin, oprelvekin, pravastatin, prazosin, quinapril, ramipril, saruplase, simvastatin, terazosin, valsartan, or verapamil.

In another aspect, the invention relates to treatment of migraine or non-migraine headache by administration of a CRF antagonist in combination with a non-CRF antagonist compound that treats such condition. For example, it is possible to administer a CRF antagonist with non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin, acetaminophen, ibuprofen, with anti-emetics, with preparations containing ergotamine such as dihydroergotamine, or with agents that modulate serotonin receptors (including those that modulate the 5HT_(1B), 5HT_(1D), 5HT_(1F) and 5HT_(2B) receptors) or that mimic the effects of serotonin. Particular agents include sumatriptan, naratriptan, zolmitriptan, rizatriptan, eletriptan, and almotriptan. Administration of these compounds is carried out using dosages and formulations that are well-known.

In another aspect, the invention relates to treatment of emesis using a CRF antagonist in combination with a non-CRF antagonist compound for treating emesis. Examples of such non-CRF antagonist compounds for treating emesis include tachykinin antagonists, including Nk1 antagonists, (such as compounds described in WO 99/24423, EP 867182, EP 980324, and WO 99/24423) and 5HT₃ antagonists (such as metoclopramide, granisetron, dolasetron, ondansetron and tropisetron).

The emesis that is treated can be of any type, including emesis induced by pregnancy, vestibular disorder, post-operative sickness, gastrointestinal obstruction, reduced gastrointestinal motility, visceral pain, migraine, change in intercranial pressure, chemotherapy, radiation, toxins, and opioid analgesics.

The invention also encompasses combined pharmaceutical compositions containing the CRF antagonist, a non-CRF antagonist as defined above, and below, and a pharmaceutically acceptable carrier. Examples of such compositions include, without limitation:

1) a composition for treating abnormal circadian rhythm that contains effective amounts of a combination of a CRF antagonist and a non-CRF antagonist compound useful for treating abnormal circadian rhythm;

2) a composition for treating depression that contains effective amounts of a combination of a CRF antagonist and a second compound for treating depression that has a delayed effect;

3) a composition for treating or preventing a cardiovascular disease that contains effective amounts of a CRF antagonist in combination with a second, non-CRF antagonist compound for treating the disease;

4) a composition for treating migraine or non-migraine headache that contains effective amounts of a CRF antagonist in combination with a non-CRF antagonist compound that treats such condition; and

5) a composition for treating emesis that contains a CRF antagonist in combination with a non-CRF antagonist compound for treating emesis.

Combination treatments according to the invention can be administered as part of the same pharmaceutical composition, or the active agents can be administered separately as part of an appropriate dose regimen designed to obtain the benefits of the combination therapy.

Acid addition salts of the CRF antagonists and other agents employed in the invention can be prepared in a conventional manner by treating a solution or suspension of the corresponding free base with one chemical equivalent of a pharmaceutically acceptable acid. Conventional concentration or crystallization techniques can be employed to isolate the salts. Illustrative of suitable acids are acetic, lactic, succinic, maleic, tartaric, citric, gluconic, ascorbic, benzoic, cinnamic, fumaric, sulfuric, phosphoric, hydrochloric, hydrobromic, hydroiodic, sulfamic, sulfonic acids such as methanesulfonic, benzene sulfonic, p-toluenesulfonic, and related acids.

The CRF antagonists and their pharmaceutically acceptable salts, and any second pharmaceutically active compounds, may be administered alone or in combination with pharmaceutically acceptable carriers, in either single or multiple doses. Suitable pharmaceutical carriers include inert solid diluents or fillers, sterile aqueous solutions, oils (e.g., peanut oil, sesame oil) and various organic solvents. The pharmaceutical compositions formed by combining the CRF antagonists and pharmaceutically acceptable carriers can be readily administered in a variety of dosage forms such as tablets, powders, lozenges, emulsions, oil soft gels, syrups, injectable solutions and the like. These pharmaceutical compositions can, if desired, contain additional ingredients such as flavorings, binders, excipients and the like. Thus, for purposes of oral administration, tablets containing various excipients such as sodium citrate, calcium carbonate and calcium phosphate may be employed along with various disintegrants such as starch, methylcellulose, alginic acid and certain complex silicates, together with binding agents such as polyvinylpyrrolidone, sucrose, gelatin and acacia. Additionally, lubricating agents such as magnesium stearate, sodium lauryl sulfate and talc are often useful for tabletting purposes. Solid compositions of a similar type may also be employed as fillers in soft and hard filled gelatin capsules. Preferred materials for this include lactose or milk sugar and high molecular weight polyethylene glycols. When aqueous suspensions or elixirs are desired for oral administration, the essential active ingredient therein may be combined with various sweetening or flavoring agents, coloring matter or dyes and, if desired, emulsifying or suspending agents, together with diluents such as water, ethanol, propylene glycol, glycerin and combinations thereof.

For parenteral administration, solutions containing the CRF antagonist or a pharmaceutically acceptable salt thereof in sesame or peanut oil, aqueous propylene glycol, or in sterile aqueous solution may be employed. Such aqueous solutions should be suitably buffered if necessary and the liquid diluent first rendered isotonic with sufficient saline or glucose. These particular aqueous solutions are especially suitable for intravenous, intramuscular, subcutaneous and intraperitoneal administration. The sterile aqueous media employed are all readily available by standard techniques known to those skilled in the art.

The effective dosages for the CRF antagonists employed in the methods of this invention will depend on the intended route of administration and factors such as the age and weight of the patient, as generally known to a physician. The dosages will also depend on the particular condition to be treated and will generally range from about 0.1 to about 300 mg/kg body weight of the patient per day, with administration carried out in single or divided dosages.

Methods that may be used to determine the CRF antagonist activity of the compounds employed to practice the invention are described e.g., in Endocrinology, 116, 1653-1659 (1985) and Peptides, 10, 179-188 (1985).

Methods that can be used to determine the CRF binding protein inhibiting activity of compounds employed to practice the invention are described in Brain Research, (1997), 745(1,2), 248-256. The binding activities of the CRF antagonists employed generally range from about 0.5 nanomolar to about 32 micromolar.
